ALS Landing lights are visible in Multiple Views

[sathish]

Hi,
While Enabling Landing Lights in Flightgear 2017.3.1 with multiple view configurations(Center,Right,Left), instead of appearing on Center view the landing light spots are visible on all the three views ...
I couldn't able to Disable the multiple Light spots ...Any Shader or Effects updation is required..
Can Anybody help me to sort out this..

Thanks in Advance

I'm not sure I totally understand your question, but I think your wanting to limit the ALS landing lights to center view only?

Something like this logic statement works well.

In file als-lights.xml

Code: Select all

<logic>
        <name>ALS Lighting Landing</name>
        <input>
            <and>

               <!-- change the following view condition to match the view you want the lights to be visible with -->
                <property>/sim/current-view/internal</property>

               <!-- this would be your switch that turns on the landing light -->
                <property>/sim/model/c172p/lighting/landing</property>

            </and>
        </input>
        <output>
            <!-- this is the switch that turns on the ALS landing light shader -->
            <property>/sim/rendering/als-secondary-lights/use-landing-light</property>
        </output>
    </logic>

Call it using a systems/property-rule in the set. file...

Code: Select all

<systems>
            <property-rule n="102">
                <path>Aircraft/c172p/Systems/als-lights.xml</path>
            </property-rule>
</systems>

i'm not sure but i think what the OP is calling "views" is actually separate monitors... wouldn't they be called "cameras" in FG? i may be misunderstanding this completely, too...

[wlbragg]

Oh, OK, this still may work if the two monitors that are defined as left and right are actually defined and visible if using the view properties set to true. It should still eliminate the ALS if that achieved by a camera "view". However, all three views at the same time, I have no clue if that changes things, I have never set up multi-monitors.

Thanks a lot..i'll try it..can u list the shaders responsible for ALS..

It's been awhile since I looked at any shader code, so unfortunately I can't provide you with a list of which shader files deal with landing lights.
